Adding Octane to rhino display modes.

[splittmatt]

Is it possible to add Octane as a display mode in Rhino? This should give the ability to control things like whether dimensions and curves (lines) are visible in the render, great for generating illustrations. I know Vray and Neon have this option.

Is there a work around if not?

Hi. Octane will render the geometry that is visible in the Rhino viewport. So you can switch off curves by assigning them to a layer a turning that layer off. But I will look at implementing detection of the render options - shoulnt be too hard.

This would indeed be fantastic!

Hi Paul.

What I meant was the ability to make curves renderable so you can chose whether/how you see them in the render.

For example I have 2d curves applied to faces that represent shutlines/shadow gaps. I don't want to cut the faces and the applyshutlining in Rhino doesn't handle this amount of shutlining (it's a large model) and the model is being made to generate 2d plans and sections anyway so the shutlines don't show up. So what I want to do is to have the curves render in Octane and leave the curves in place for the 2d drawings.

This could be applied to any dimensions/annotations that are added in the scene. It would be great to have them all renderable.

Hope this makes sense.

I see what you are looking for now - and unfortunately I don't think it is possible. Octane needs to have 3d geometry in order to render - it will not work on lines, arcs, etc. So in Rhino it is necessary to convert the 3d lines to Curve Piping (which is effectively adding a radius to the line to construct 3d geometry). But Octane does not currently render 2d objects - they must be 3d. The plugin geometry loading process "sees" the 2 elements, but without a "radius" or thinkness, there is not much it can do with those elements.

Without seeing the actual scenes you are working with, it's a bit hard to visualize a solution. But some options that you could pursue...

1) Bake the curves onto the surface's diffuse material texturemap (I could not work out how to do this with Rhino, but can be done with some other 3d modelling apps - or there is probably a Rhino plugin to do this), or

2) Write a script which automatically converts all the 2d geometry to curve piping/shutlining. So the 2d version would be the master, and then you would convert from 2d to 3d for rendering.

So in summary - I'm certain a solution could be found - but it would most likely be not a modification to the plugin, but be a Rhino scene processing operation. And it might require to need to do some scripting or R&D.
